Update-


Well so far, I'm getting over being sick and falling back into the school groove, which means things should be back on track soon.

So this is what I have been doing so far:


Tore down the engine to an almost bare block, just have to get that ridiculously large nut off the fly wheel and then crack her open to measure.

I also have been sandblasting parts here and there, working on a few more, but this is what I have so far.


So here's is the Engine in all her dirty glory:

Another lovely side view of her:

The oil pan, which is so damn clean, it looks like brand fucking new:

And last but not least, the sandblasted stuff that needs to be painted with good old flat black rustoleum!

I have a socket for the flywheel nut, do you have an impact gun?

We have "big Bertha" at the school a 3/4" drive impact gun, don't worry about the socket, I bet you the tool room has it buried somewhere. Thanks though :)

Ok, just look for 2-1/8 inch socket

i believe we have a 2-1/8th inch.. but the prob is i doubt its an impact socket. ask ron or i can come to the toolroom and get it.

I sadly didn't not get the engine cracked open on Thursday, our tool room did not have the socket, but my engine teacher is bringing one for Tuesday's night class. Of course our 3rd member of our group wasn't there Thursday night, and I forgot the combination to our locker; so I couldn't even clean the intakes and stuff...

Well I got some stuff done at least today...

Was slow at work so I went ahead and disassembled my rotors from my spindles and cleaned them up so that I can go ahead and sandblast and paint them also sometime next week.

My boss calls me in and says they made a accounting error and they owed me quite a bit of money... can you say "The bank has made an error in your favor, pass go and collect $800." so money is starting not to be as big an issue as it was the beginning of this long project. So thankfully I should be fairly prepared in case of any surprises with the engine or the restoration of my RX7.

Sorry for the lack of pictures guys, I'll keep you updated on the progress.

hey you still gonna go with the same rear end? i might get another rear end. if you want to put se stuff in it :P

As far as I can tell the axle that I pulled from my '82 is not the stock axle that came with that car because:

1.) its running an LSD
2.) I have disc brakes installed on the axle.

I've had a pain in the ass time trying to identify my 1982 for what it was orginally, and gave up...

but from the looks of it, I'm just going to stick with the axle I have now, after all LSD and Disc brakes? those will be fine until I decide to go for more power later on down the road, ya know?

Okay Guys, been a while since an update and I've been lazy as hell in trying to keep this updated.

But! I did manage to get stuff done so I am happy about that!

I media blasted some more parts, painted my battery tray in Black Matte Rustoluem (It looks nice, I'll take pictures after I do a few more pieces), Waiting on some rubber bushings before the front brakes get rebuilt and painted.

Most importantly though, I finally cracked open the engine and I must say that it was a learning experience. The housings and other bits actually looked pretty good when I started getting everything apart, but I haven't started measuring and cleaning everything up yet.

That's the next step, will try and get some cleaning and such done tuesday.

and now for some pictures to tide you over until I take better quality pictures next week:

The Front Rotor inside the housing with the intermediate plate removed, it actually looks fairly okay, at least at first glance, we'll see how bad it is next week!
http://i230.photobucket.com/albums/e...05-09_2122.jpg

And no those two rings at the bottom of the picture are not scores, its actually some oil sheen and such from be being dirty.

Looking good, keep it up. I hope your going to port it while your in there.

I have thought about porting it, but I'm not sure which to do and how much I really want to spend on that... :Wconfused

if you're not sure, then dont do it. project is big enough anyways

i would just get it running first, then buy a TII sometime later

Well, I'm open to suggestions?

I mean, essentially all I am doing is cleaning and refurbishing the engine right now. Unless someone has some suggestions for improvements?

Tomorrow I am going to try and finish painting what I have so far, will post pictures when I get them done.

Good god? How hard is it to find some freaking guide pin bushings!?

I tried every parts store I know of and I thought I got the right part from Rock Auto, ended up they send me two bolts for the calipers...

Anyone else ever have this much trouble trying to get replacement bushings?!

wtf? wow.

i saw the engine monday, looks alright.

which class are you in? morning or nights?

Night classes

guide pin bushing?

Well sorry I haven't been updating much... I've been dealing with some personal issues and this rain is really hampering a lot of the work I can do.

I finally got my front calipers torn down and cleaned up, so now the brake parts need a coat of Caliper Paint.


In any case, its late right now, but I will try and snap some photos for you guys tomorrow and update the thread with what's been going on in terms of the project.

Okay, thank the gods that today was a fairly nice sunny day! I actually got a ton of painting done today because I was afraid that we might not see sunlight for a while after today.

In any case, all the brake parts got a coat of DupliColor Black Caliper paint, the crossmember, control arms, battery tray, and other bits got coated in Rustoleum Textured Black Satin to prevent rust mainly.

I don't have any pictures of the engine right now, mainly because its in pieces... though I did manage to finally measure everything and it looks like its still good condition. The apex seals are about 7-7.5mm average, but I am going to go ahead and wait for my next pay check and buy a master rebuild kit, I'll post pictures and such when I am installing everything.

In the meantime how ever, I am expecting some parts today so if all goes well then all these painted pieces should be assembled tomorrow into a full front suspension!

And now for the one picture that screams Black:
http://i230.photobucket.com/albums/e...7/DSC00421.jpg

Oh, also... I am machining the rotors tomorrow so they'll be nice and paint free where the pads need to make contact.

So I didn't get everything I would have liked done today, a lot of other classwork got in the way of that...

But I did manage to install the ball joints, poly urethane lower control arm bushings, rebuild the calipers, and get the old races for the bearings out.

I still need to install and pack the new wheel bearings, machine the rotors, and then assemble the front suspension.

Not bad for like an hour or two or work. I can probably get the rest done tomorrow on lunch break or something if I can.

Well I can take pictures of the stuff if you want, it hasn't really changed that much from the above picture. BTW that poly urethane lubricant is sticky as hell...

Well today was a slow day and I probably only worked on 2 or 3 cars and spent some 6 hours of my 9 hours of work twiddling my thumbs. So at lunch I went home and grabbed my Blazer and brought all the parts over to work, I figured if I wasn't going to be working, might as well take advantage of the shop's tools. Sometimes Flat Rate sucks...

So after punching out the old bearing races, I spent a good 20 minutes trying to figure out how to get the weirdly shaped rotors onto our machine. After figuring it out I went ahead and turned them to a nice new finish. Now that the rotors were ready to be installed, it was time for the fun messy part; packing the bearings. I actually love packing bearings, for some odd reason the grease feels fun to squeeze, I just hate the damned clean-up after words.

After getting the rotors onto the spindles, I went ahead and installed the original brake pads onto the bracket and then added the rebuilt calipers over them. Side note here, why Mazda decided to make their guide pins the way they did on these first gens confuses the hell out of me. I think my next set of brakes in the future are going to be just 4 pots, I hate dealing with guide pins seizing and such.

The control arms and ball joints went together rather easily and didn't give me too much crap. I already installed the RE-Speed Poly bushings for the lower control arm. The strangest problem I came across was actually with my Moog Tie Rods! They have a nipple that seems to be sliced on all the tie rods, now we were all thinking it has to be a vent because they have zerk fittings on them to relieve pressure if you inject too much grease. But just moving them around produces an obscene amount of grease squirting out of that nipple, is this normal or some sort of defect? It doesn't seem like that much grease should be escaping.

I didn't have enough time to mount the control arms to the crossmember, but I will go ahead and do that tomorrow if its slow again or after work. Now for the pictures!:

The final product, two complete strut assemblies ready to bolt into the crossmember and car:

Now here's the tie rod before I took it back off to double check them. You can see the grease starting to squirt out with little pressure other than seating the ball joint onto the knuckle:

I know most of you don't really care for this thread but, I figured that if anyone actually cared I would still update it... worst case scenario, I at least feel like I am doing something.

Looking good!
Makes me want to start working on my "Mariah"

Hey! Where in Sweeden do you live? my grandparents live in Helsingbør

Well I am almost to the point where I can prep the engine parts to paint them pretty colors before the rebuild kit gets ordered....

That is if I can get these god damn gaskets off, I mean good god what the hell are they made from!? I've tried soaking them, scraping, using gasket remover products, hell even a razor blade. Its like the damned things are made from frickin' concrete!


Well, in any case I'll figure that out eventually...

Anyways! What colors should I paint the engine? I was thinking Black/Green... but I can't find any Silicone hoses that come in green. So any color suggestions?

Gaskets on the irons or the oil pan?

The irons, I can't get the gaskets off the water pump housing, the front,middle, and rear irons, and the intake manifold. :wallbash:

They seem like simple fibrous gasket material, but the stuff is like concrete, if I soak it only the top layer gets easy to take off, the rest is still stuck there pretty bad..

did you try and use gasket remover?

If so then try a wire wheel on a drill or grinder.

we will probably use our new precision cnc grinder on it

The problem is more the Aluminium bits, like the intake manifold (All three parts) and other aluminium pieces... we can't wire wheel those without resurfacing afterwards.

The gasket remover doesn't soak more than a couple thousandths into the gasket. :wallbash:

you need one of those scotchbrite discs, http://www.levineautoparts.com/3mrolsurcond.html like those. or you can go old school and just scrape for hours....

a little silicon on the gasket when you put it together keeps this from happening next time

i'll see if we can order these for you

i just aligned Mr Peepers this weekend, and the threaded part of the tie rod ended up at about 2 1/16". same on both sides. the actual number will vary slightly depending on what toe angle you want, and how bent the car is....

Well I am in a very foul mood right now...

Someone went into the trailer park and stole my wheels and catalytic converter while it was raining.

The part that really pisses me off is that where the car is sitting is smack in the middle of the trailer park and what they stole they had to unbolt some of it! If you guys remember the exhaust system was so rusted together I had to drop it as an entire assembly! So the thief took their time to unbolt the cat from the exhaust and steal it. Then they took the two front wheels and the large brown tarp I had on the ground, I am finding it hard to believe that no one noticed this happening and am in a very very bad mood over it.

The cat I could let go, but those stock 13" Plus rims going missing just put making this chassis rolling to a halt, especially since I just got my hours cut back at work due to the rescission, so I have to really start scrounging money after I buy the rebuild kit for the 13B.

So until I can score some replacement rims with tires or find what went missing, the only updates might be the engine right now.

If your room is near where your car is and such, pay attention to noises when your around, you were probably at class though.

I had a stalker when him and his friends came and threw shit at my house i was right out there with a nam buck knife ready to slit their throats.

Fuck trespassers, and great thread keep it up man I'm reading :)

The trailer park is owned by my stepdad, I live about 5 miles away. Its been raining for the past 2-3weeks so I haven't had the cars because of where they are. If they were at my house no one would have fucked with them.

Man that sucks, what are they gonna do with a 4x110 bolt patter set of rims? What a bunch of stupid fags man. I feel your pain.

do you still have that other front sway bar? i'd buy it off of you if it helps you at all...

Here's a question, I didn't think it was really necessary to make a separate thread for it, since I'm sure that the answer will be rather quick.

What is a good Aftermarket Catalytic Converter for a '86 13B? How many do I need to install for a good smog?

I've pretty much laid off the suspension and frame work since my wheels got stolen, so I ordered the rebuild kit and was thinking about drafting up some ideas for a new 2.5" exhaust system.

Any help would be appreciated?

if you have the factory smog equipment, or just the air pump blowing into the exhaust ports, it will pass with 1 main cat.

hell i got that same car to pass with an air pump and some used POS main cat i found in the yard. it failed the first time cause its missing the big heat shield and it tripped the heat hazzard sensor, which dumped a ton of fuel in the middle of the run.

so i went home, unbolted the sensor and tossed it over the roll bar, and it passed.

without that shield it gets HOT inside, i believe when they took it to mazdafest in 06 it melted shoes...

anywho, look in like the magnaflow website, or maybe summit/jegs.

technically in california its supposed to have 2 precats too, but it doesnt need those to pass, and hardly anyone knows or cares as long as it passes out the tailpipe

That was my main concern Jeff, the two pre cats made me wonder if I was going to need a second cat to get the same effect.

As for the main cat? I still have all the exhaust heat shielding and will most likely try to put the after market cat where the original was. Sadly though, in California you can no long buy "used" cats which even includes re-cored cats.

Any suggestions on who would be a good brand to consider?

Hey! Lookie what I got in the mail!

Yes that is the Atkins Rotary 6 Port 13B Kit C!

http://i230.photobucket.com/albums/e.../AtkinsKit.jpg

But before we start rebuilding the engine, its time to make sue she's painted properly in Flat Black and Clear VHT Header paint!

http://i230.photobucket.com/albums/e...tedHousing.jpg

Stay tuned for more updates! :)

Sweetness. It always pays off in the long run to replace all that you can. That way your engine will be more reliable, and last alot longer. Good job!

nice ... keeping an eye open for this one

sweet man

sorry about your rims and cat

i'm not sure but it seems like there are only 2 different ones, bosal makes em, and magnaflow/catco/etc etc etc makes em.

just find the size you want, and get the cheapest one

Okay guys, here's an update for you all...

I got the front and intermediate plates painted with the VHT Flat Black Flame Proof Header Paint and then don't look to bad. I'm going to clear coat the aluminum bits and the whole engine with the VHT Flame Proof Clear Coat after I assemble it to give it a sort of semi-gloss look.

My question is though, how does one polish the outside housings? I tried some fine steel wool, but that didn't seem to do anything really...anyone have ideas? tricks?

So without further ado, here's a pic or two to satisfy you guys until I get my front suspension in or I start rebuilding the motor, which ever comes first.


The painted irons in all their charcoaly glory!

and a better picture of how easy it is to store your rotary motor in a metal cabinet!
http://i230.photobucket.com/albums/e...67/Cabinet.jpg

hey, nice build up. sorry to hear bout your wheels. where are you building ur motor? looks like a class room.

btw, i have a set of 4 stockies if you want. let me know and they're yours

Yeah I'm rebuilding the engine in my college's classroom.

Thanks for the offer on the wheels, I found some replacements in the junkyard sans center caps.


BTW Does anyone have any ideas for how to polish the aluminum nicely?
